Coleus canina: save £4

An attractive foliage plant, Coleus canina also has a smell abhorrent to cats. The plant has striking grey-green foliage, which gives off a strong aroma especially when touched and in summer it produces heads of lovely pale blue flowers. If planted in a container this can be moved around the garden protecting different areas from cats. Thankfully it only smells to humans when touched.

We are offering five healthy plug plants for just £8.95. Alternatively, buy ten for £13.90, saving £4. For a bumper collection buy 20 for £22.80, saving a further £5.
